Molecular Mechanisms Underlying Environmental Enrichment-Induced Neuroprotection In Vulnerability To Nicotine Addiction, Adrian Michael Gomez

Theses and Dissertations

Tobacco use is the number one preventable cause of death in the world. Nicotine is the principal, addictive component in tobacco responsible for its reinforcing properties that drive the behavioral manifestations of nicotine addiction. Environment is becoming increasingly implicated in nicotine susceptibility. However, the molecular mechanisms that underlie susceptibility to nicotine addiction remain unknown. An ideal animal model that addresses environmental factors uses rats raised in an enriched condition (EC), a standard condition (SC), and an impoverished condition (IC); which differ in novelty, social cohorts, handling, and physical activity. EC rats exhibit a neuroprotective-like phenotype in the behavioral resistance to …
